Those people are not middle class.
Middle Class IMO would be a two income household for instance one working a middle manager position at a government agency making 70K and another who is a teacher making 60K and 2-3 kids. These people are not a "paycheck" away from being homeless. They have some savings but their expenses are relatively high due to child care costs and possibly living in a relatively expensive city. In reality, these two people - who between them may only have bachelor's degrees - are relatively comfortable in the sense that they are employable, have some savings, are paying into retirement accounts etc.
The people you're talking about are most likely those who only recently started making 50-60K, after years of making 20-30. They feel relatively "richer" because of the extra income, but the years of making shyt has left them in debt and with no assets.
My point being that just because you are dissatisfied with the soci-economic direction of the country, there is no need to wallow in hyperbole. The middle class is definitely under a lot of pressure nowadays, but it's not non-existent.
